Ib cov tsog

Yog li cia li tsis tshua muaj raws li nws cov paranormal hu npe raws qab no npauj (tshwj hais tias nws yog tiag) – Nws yog ib tug Gazoryctra sp. nyob rau hauv tsev Hepialidae. Lawv sawv cev rau ib tug basal lineage ntawm cov Lepidoptera thiab feem ntau tau paub tias dab npaub los yog npaub swift. Dab – vim caug ntawm tej hom paub tias ya hauv leks muaj tseeb, qhov twg lawv yuj li down hauv hav clearings ntawm yuav luag tsaus ntuj thaum saib cov maum. Cov qub caug kuj hu rau cov pojniam uas muaj pheromones, rov qab muaj teeb meem nrog cov kab ib me ntsis. Ntxhee- theej tswj qhov tshwm tag, tab sis hom boreal paub tau haib flyers.

Rau qhov kev tso kawm ntawm tus tis rau lub cev yog ib yam ntawm cov yam ntxwv uas pab qhia tias qhov no yog ib tug lineage basal, ib co koojtis venation, txo los sis tsis tuaj pom lub qhov ncauj thiab cov tsis muaj ib qho koojtis coupling ntaus ntawv. Cov npaub muaj ib “jugum”, Nws yog ib tug ntiv tes xoo me me ib yam li projection los rau saum lub hindwing. Lwm lineages uas npaub muaj ib coupling nruj mechanism hu ua cov frenulum thiab cov retinaculum, qhov chaw nov khawb cov tis ob kom lawv nyob twj ywm rau coupled thaum ya davhlau. Thaum nyob so rau jugum folds ntawm thiab tej zaum yuav pab kom cov tis ua ke – tab sis tsis tau thaum nyob hauv davhlau; yog tus forewing ua of sync nrog cov hindwing thiab tsis dynamic davhlau yog (Scoble 1992).

Nyob rau hauv cov Americas Hepialid ib no heev tsis to taub. Ib handful tsuas txog lub neej txog kab yog piav tas – txhua yam uas zoo li yuav endophagous (tho txawv) Thaum cog lub cag. Tej thaum ntxov instar kab yuav noj nyob rau nplooj khib los underground ntawm cov hauv paus hniav ua ntej yuav nkag mus kawm rau rhizome. Australia muaj hmoo tau tus miv thiab impressive fauna ntawm Hepialidae – muaj ntau yam brilliantly dawb thiab enormous (250hli los mus txog rau 12 nti!), thiab lub zoo tshawb nrhiav. Ib co menyuam kab twb ntau txaus uas aboriginal pab pawg neeg tau siv lawv ua ib staple mov qhov no.

Tab sis rov los no npauj lawm hauv particular. Kuv yuav tsum ntim nws hauv kuv lub teeb dub cuab lub yim hli ntuj tas los no tuaj Sierra Nevada pib ib ncig 10,500 ko taw. Yog tsis paub hom kab, thiab tej zaum yuav ze li tshiab. Ib sab feem ntau frustrating no mas tsuas kuaj pom cov kev kawm. Lub genus tag nrho yog tsawg kawg, tsuas yog ib tug los yog ob tug commoner hom, xwb ob peb dozen nrws nyob ua ib ke. Li ntawd, yog ib tug poj niam rau ib hom qhia los ntawm ib tug txiv neej? Aberration freakish ntawm tus otherwise paub hom? Los sis tej zaum nws tseem ua tau tshiab. Kuv twb barcoded ua tus DNA, uas tau qhia rau kuv tsis muaj dab tsi vim muaj pes tsawg lub sequences los ntawm tej yam zoo hom. Ua tau, raws li kuv paub, rau lwm hom rau cov Sierra tsis txawm tau los hauv xyoo lawm ces kuv tsis tseem tau txais raws qib raws dua ib ntawm tus hlob mus. Cov icing rau lub ncuav mog qab zib yog lawv tus cwj pwm. Lawv tsis tshua, yog puas, tuaj sib – uas tej zaum yuav ntog ib cov crepuscular ya davhlau. Nyob rau txoj kev tsaus ntuj lawv, tej zaum yuav tis rau 20-30 feeb, feem ntau yog ib tug poj niam searching paub ib tug txiv neej, los yog ib tug poj niam ya mus oviposit (tej zaum yuav yog vim broadcast scatter qe rau hauv av). Thiaj tuaj no lig lub yim hli ntuj kuv mam yuav rov mus lub siab Sierra nrog ob peb tuaj pab dawb los ntawm lub tuam tsev entomology xim pom ib whiz ntawm kuv nyob rau lub slopes ntseg. Yog hais tias kuv tau ib txhia tshaj, nws ua dab tsi yuav impressive tshiab hom rau California.
